RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description lethalwp 2021-12-15 15:59:38 UTC 
Description of problem:
when using virt-manager to manage & use virtual machines, qemu-kvm crashes.


Version-Release number of selected component (if applicable):


How reproducible:
every time

Steps to Reproduce:
1. install c9stream
2. open virt-manager  create a new dummy machine example: win10, 512MB RAM, 1cpu, 1GB hdd
3. the virtual machine can't have a graphical server of SPICE (why was this deprecated???? it works perfectly on my fedora 35). So it has a gfx of "VNC"
4. if you close the config/console window, press play, the machine will boot up
5. as soon as you connect to the gfx console, qemu-kvm will coredump.

Actual results:
coredumps & stops the VM
There is no abrtd in C9S to automatically fill a bug report???


Expected results:
connecting to the VM
